MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

 
 RESULTS OF OPERATIONS 

Net Income 
 Net income attributable to common shareholders for
the quarter ended September 30, 2018 of $194 million is a decrease of $25 million or 11.4% from the prior year. Significant influences on net income included: 
  

	 	•	 	 increase in transmission and distribution revenues due to higher energy consumption resulting from favourable weather;



  

	 	•	 	 lower transmission revenues driven by the timing of Ontario Energy Board (OEB)‘s decision on the 2017-2018
transmission rate filing, which resulted in recognition of year-to-date revenues in the third quarter of 2017, partially offset by increased OEB-approved transmission rates; 


  

	 	•	 	 lower OM&A costs primarily resulting from lower costs related to the acquisition of Avista Corporation (Merger),
savings related to the renewed information technology (IT) outsourced contract, lower customer programs costs; partially offset by higher corporate support costs; 



 

	 	•	 	 higher financing charges primarily due to revaluation losses on the deal-contingent foreign exchange forward contract,
and an increase in interest expense on long-term debt and on the convertible debentures issued in August 2017; and 


  

	 	•	 	 higher income tax expense primarily attributable to a combination of an increase in the estimated annual effective tax
rate (ETR) for 2018 arising from higher forecast earnings coupled with a corresponding decrease in the estimated annual ETR for 2017 arising from lower forecast earnings. 



Net income attributable to common shareholders for the nine months ended September 30, 2018 of $616 million is an increase of $113 million
or 22.5% from the prior year. Significant influences on net income included: 
  

	 	•	 	 increase in transmission and distribution revenues due to higher energy consumption resulting from favourable weather;



  

	 	•	 	 higher transmission revenues driven by increased OEB-approved transmission rates;



  

	 	•	 	 lower OM&A costs primarily resulting from lower costs related to the acquisition of Avista Corporation, savings
related to the renewed IT outsourced contract, lower customer programs costs, lower storm restoration costs and timing of work programs; partially offset by higher project write-offs due to revision of asset replacement strategies and alternatives
not pursued; 


  

	 	•	 	 higher financing charges primarily due to an increase in interest expense incurred on the convertible debentures issued
in August 2017 and on short-term notes payable, partially offset by revaluation gains on the deal-contingent foreign exchange forward contract and a decrease in interest expense on long-term debt; and 



 

	 	•	 	 higher income tax expense primarily attributable to a combination of an increase in the estimated annual ETR for 2018
arising from higher forecast earnings coupled with a corresponding decrease in the estimated annual ETR for 2017 arising from lower forecast earnings. 



EPS and Adjusted EPS 
 EPS was $0.33 and $1.03 in the three and
nine months ended September 30, 2018, respectively, compared to EPS of $0.37 and $0.85 in the comparable periods last year. The changes in EPS were driven by changes in net income for the three and nine months ended September 30, 2018, as
discussed above. Adjusted EPS, which adjusts for income and costs related to Avista Corporation acquisition, including the gains and losses on the deal-contingent foreign exchange forward contract, was $0.38 and $1.06 in the three and nine months
ended September 30, 2018, compared to $0.40 and $0.88 in the comparable periods last year. The changes in Adjusted EPS were driven by changes in net income for the three and nine months ended September 30, 2018, as discussed above, but
exclude the impact of items related to Avista Corporation acquisition. See section “Non-GAAP Measures” for description of Adjusted EPS.

 Transmission Revenues 

Transmission revenues increased by 4.7% for the quarter ended September 30, 2018 primarily due to the following: 

 

	 	•	 	 higher average monthly Ontario 60-minute peak demand primarily driven by
favourable weather in the summer of 2018; and 


  

	 	•	 	 increased 2018 allowed return on equity (ROE) for the transmission business; partially offset by 



 

	 	•	 	 lower revenues driven by the timing of the OEB’s decision on the 2017-2018 transmission rate filing, which resulted
in recognition of year-to-date revenues in the third quarter of 2017; partially offset by increased OEB-approved transmission
rates for 2018; and 


  

	 	•	 	 lower deferred regulatory adjustments. 



The increase of 12.1% in transmission revenues for the nine months ended September 30, 2018 was primarily due to the following: 

 

	 	•	 	 higher average monthly Ontario 60-minute peak demand primarily driven by
favourable weather in May, June and the summer of 2018; 


  

	 	•	 	 higher revenues driven by increased OEB-approved transmission rates for 2018; and



  

	 	•	 	 increased 2018 allowed ROE for the transmission business; partially offset by 



 

	 	•	 	 lower deferred regulatory adjustments. 



Distribution Revenues, Net of Purchased Power 

Distribution revenues, net of purchased power, increased by 1.4% for the quarter ended September 30, 2018 primarily due to the following: 

 

	 	•	 	 higher energy consumption resulting from favourable weather in the summer of 2018; partially offset by



  

	 	•	 	 lower external revenues in 2018 primarily due to revenues received in 2017 for Hurricane Irma restoration assistance
efforts in Florida. These restoration efforts had no impact on the Company’s net income, as related costs were recorded in distribution OM&A during the third quarter of 2017; and 



 

	 	•	 	 lower deferred regulatory adjustments. 



The increase of 2.0% in distribution revenues, net of purchased power, for the nine months ended September 30, 2018 was the result of similar factors
as noted above.

 Transmission OM&A Costs 

Transmission OM&A costs for the quarter ended September 30, 2018 were comparable to prior year, and were primarily impacted by the following:

  

	 	•	 	 insurance proceeds received for the National Research Council (NRC) transformer station; 



 

	 	•	 	 lower costs related to the renewed IT outsourced contract;

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

 

	 	•	 	 higher volume of work on vegetation management; 



 

	 	•	 	 higher project write-offs due to revision of asset replacement strategies and alternatives not pursued; and



  

	 	•	 	 higher corporate support costs. 



Transmission OM&A costs for the nine months ended September 30, 2018 were comparable to prior year, and were primarily impacted by factor noted
above, as well as lower volume of work on environmental management. 
 Distribution OM&A Costs 

Distribution OM&A costs for the quarter ended September 30, 2018 were comparable to prior year, and were primarily impacted by: 

 

	 	•	 	 lower storm restoration costs in 2018 as a result of Hurricane Irma restoration assistance efforts in Florida in 2017.
These restoration efforts had no impact on the Company’s net income, as related revenues were recorded in distribution revenues during the third quarter of 2017; 



 

	 	•	 	 lower costs associated with customer programs, primarily related to the Call Center and a lower volume of field
collections and investigations as a result of extended winter moratorium; 


  

	 	•	 	 lower costs related to the renewed IT outsourced contract; 



 

	 	•	 	 higher spend on vegetation management; 



 

	 	•	 	 higher volume of emergency calls; and 



 

	 	•	 	 higher corporate support costs. 



The decrease of 2.7% in distribution OM&A costs for the nine months ended September 30, 2018 was primarily due to the following: 

 

	 	•	 	 lower storm restoration costs; 



 

	 	•	 	 lower costs associated with customer programs, primarily related to Call Center, less demand for low income assistance
program and a lower volume of field collections and investigations as a result of extended winter moratorium; 


  

	 	•	 	 lower costs related to the renewed IT outsourced contract; 



 

	 	•	 	 lower bad debt expense; partially offset by 



 

	 	•	 	 project and inventory write-offs due to revision of asset replacement strategies, alternatives not pursued, and obsolete
inventory and technology; and 


  

	 	•	 	 higher volume of emergency calls. 



Other OM&A Costs 
 The decrease in other
OM&A costs for the quarter and nine months ended September 30, 2018 was primarily due to lower consulting and contract costs related to the acquisition of Avista Corporation, partially offset by higher labour costs. 

Financing Charges 
 The increase of $35 million or 30.7% in
financing charges for the quarter ended September 30, 2018 was primarily due to the following: 
  

	 	•	 	 an unrealized loss recorded in the third quarter of 2018 due to revaluation of the deal-contingent foreign exchange
forward contract related to the Avista Corporation merger; 


  

	 	•	 	 an increase in interest expense related to the convertible debentures issued in August 2017; and 



 

	 	•	 	 an increase in interest expense on long-term debt driven by higher long-term debt balance outstanding during the third
quarter of 2018. 


 The increase of $16 million or 5.0% in financing charges for the nine months ended September 30, 2018
was primarily due to the following: 
  

	 	•	 	 an increase in interest expense related to the convertible debentures issued in August 2017; and 



 

	 	•	 	 an increase in interest expense on short-term notes payable driven by higher weighted average interest rates and balance
of short-term notes outstanding in 2018; partially offset by 


  

	 	•	 	 an unrealized gain recorded in 2018 due to revaluation of the deal-contingent foreign exchange forward contract related
to the Avista Corporation merger; and 


  

	 	•	 	 a decrease in interest expense on long-term debt driven by lower long-term debt balance outstanding in 2018.



 Income Tax Expense 
 Income tax expense
was $41 million and $115 million for the three and nine months ended September 30, 2018, respectively, compared to $23 million and $73 million in the same periods of 2017. The Company realized an ETR for the three and nine
months ended September 30, 2018 of approximately 17.1% and 15.4%, respectively, compared to approximately 9.3% and 12.3% in the same periods last year.

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

As prescribed by the regulators, the Company recovers income taxes and is required to accrue its tax expense based on the tax liability determined without
accounting for temporary differences recoverable in the future from customers. The annual ETR is re-forecast at each interim reporting period and can fluctuate based on the change in forecast annual earnings
at the conclusion of each reporting period. 
 The increase in income tax expense for the three and nine months ended September 30, 2018 was
primarily attributable to a combination of an increase in the estimated annual ETR for 2018 arising from higher forecast earnings coupled with a corresponding decrease in the estimated annual ETR for 2017 arising from lower forecast earnings.

 Variations in revenues and net income over the quarters are primarily due to the impact of seasonal weather conditions on customer
demand and market pricing, as well as timing of regulatory decisions. 
 CAPITAL INVESTMENTS 

The Company makes capital investments to maintain the safety, reliability and integrity of its transmission and distribution system assets and to provide
for the ongoing growth and modernization required to meet the expanding and evolving needs of its customers and the electricity market. This is achieved through a combination of sustaining capital investments, which are required to support the
continued operation of Hydro One’s existing assets, and development capital investments, which involve both additions to existing assets and large scale projects such as new transmission lines and transmission stations.

Future Capital Investments 
 Following is a summary of estimated
capital investments by Hydro One over the years 2018 to 2022. The Company’s estimates are based on management’s expectations of the amount of capital expenditures that will be required to provide transmission and distribution services that
are efficient, reliable, and provide value for customers, consistent with the OEB’s Renewed Regulatory Framework. The 2019 transmission capital investments estimates differ from the prior year disclosures, representing a decrease of
$158 million to reflect Hydro One’s recent one-year inflation-based application for 2019 transmission rates. The projections and the timing of 2020-2022 expenditures are subject to approval by the
OEB.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

 
 SUMMARY OF SOURCES AND USES OF CASH 

Hydro One’s primary sources of cash flows are funds generated from operations, capital market debt issuances and bank credit facilities that are used
to satisfy Hydro One’s capital resource requirements, including the Company’s capital expenditures, servicing and repayment of debt, and dividend payments.

	  	 	(632	) 	 	 	589	 	 	 	588	 	 	 	572	 

 Cash provided by operating activities 

Cash from operating activities for the third quarter of 2018 increased by $66 million compared to the third quarter of 2017, were impacted by various
factors, including higher cash earnings, and favourable changes in non-cash balances related to operations. Cash from operating activities for the nine months ended September 30, 2018 decreased by
$17 million compared to the same period in 2017, were impacted by various factors, including improved collection of accounts receivables in 2017 that reached a stabilized level in 2018, and disposition of certain regulatory variance and
deferral accounts in 2018, partially offset by higher cash earnings in 2018. 
 Cash provided by financing activities 

Sources of cash 
  

	 	•	 	 During the nine months ended September 30, 2018, the Company issued $1,400 million of long-term debt, all in
the second quarter, compared to no long-term debt issued in the prior year. 


  

	 	•	 	 The Company received proceeds of $445 million and $2,987 million from the issuance of short-term notes in the
three and nine months ended September 30, 2018, respectively, compared to $1,232 million and $2,810 million received in the same periods last year. 



 

	 	•	 	 During the three and nine months ended September 30, 2017, the Company issued $513 million of convertible
debentures, gross of $27 million financing costs, compared to no convertible debenture issuances in 2018. 


 Uses of cash

  

	 	•	 	 Dividends paid in the three and nine months ended September 30, 2018 were $141 million and $418 million,
respectively, compared to dividends of $135 million and $400 million paid in the same periods last year. 


  

	 	•	 	 The Company repaid $1,049 million and $3,469 million of short-term notes in the three and nine months ended
September 30, 2018, respectively, compared to $1,053 million and $2,385 million repaid in the same periods last year. 


 Cash used
in investing activities 
 Uses of cash 
  

	 	•	 	 Capital expenditures were $13 million higher in the third quarter of 2018 and $45 million lower year-to-date 2018, primarily due to volume and timing of capital investment work. 



LIQUIDITY AND FINANCING STRATEGY 
 Short-term liquidity is
provided through funds from operations, Hydro One Inc.’s commercial paper program, and the Company’s consolidated bank credit facilities. Under the commercial paper program, Hydro One Inc. is authorized to issue up to $1.5 billion in
short-term notes with a term to maturity of up to 365 days. At September 30, 2018, Hydro One Inc. had $444 million in commercial paper borrowings outstanding, compared to $926 million outstanding at December 31, 2017. In
addition, the Company has revolving bank credit facilities (Operating Credit Facilities) with total availability of $2,550 million maturing in 2021 and 2022, with no amounts used at September 30, 2018 or December 31, 2017. The Company
may use these credit facilities for working capital and general corporate purposes. The short-term liquidity under the commercial paper program, the Operating Credit Facilities and anticipated levels of funds from operations are expected to be
sufficient to fund the Company’s normal operating requirements. 
 At September 30, 2018, the Company had long-term debt outstanding in the
principal amount of $11,468 million which included $11,323 million of long-term debt issued by Hydro One Inc. and long-term debt in the principal amount of $145 million held by Hydro One Sault Ste. Marie LP (HOSSM). The majority of
long-term debt issued by Hydro One Inc. has been issued under its Medium Term Note (MTN) Program. The maximum authorized principal amount of notes issuable under the current MTN Program prospectus filed in March 2018 is $4.0 billion. At
September 30, 2018, $2.6 billion remained available for issuance until April 2020. The long-term debt consists of notes and debentures that mature between 2018 and 2064, and at September 30, 2018, had a weighted-average term to
maturity of approximately 15.5 years and a weighted-average coupon rate of 4.1%.

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

On June 18, 2018, Hydro One filed a short form base shelf prospectus (Universal Base Shelf Prospectus) with securities regulatory authorities in
Canada to replace the universal base shelf prospectus that expired on April 30, 2018. The Universal Base Shelf Prospectus allows Hydro One to offer, from time to time in one or more public offerings, up to $4.0 billion of debt, equity or
other securities, or any combination thereof, during the 25-month period ending on July 18, 2020. Hydro One filed the Universal Base Shelf Prospectus to provide the Company with financing flexibility
going forward. Hydro One Holdings Limited, an indirect wholly-owned subsidiary of Hydro One, expects to file in the future a short form base shelf prospectus with securities regulatory authorities in Canada and the US for the purposes of funding a
portion of the cash purchase price of the Merger. 
 Acquisition Credit Facilities 

For the purpose of bridge financing for the pending acquisition of Avista Corporation, the Company secured a $1.0 billion non-revolving equity bridge credit facility, and a US$2.6 billion non-revolving debt bridge credit facility (Acquisition Credit Facilities) in June 2018. The equity
bridge credit facility matures 90 days after the drawdown date and in any event not later than June 30, 2019. The debt bridge credit facility is available until March 31, 2019, and matures one year after the drawdown date. At
September 30, 2018, no amounts have been drawn on the Acquisition Credit Facilities. 
 Hydro One is required to make prepayments of the
Acquisition Credit Facilities in an amount equal to the net cash proceeds from any common equity, preferred equity, bond or other debt offerings, including the net proceeds from the final instalment of convertible debentures issued in August 2017,
and any non-ordinary course asset sales by Hydro One and its subsidiaries, subject to certain exceptions. Any prepayment under the Acquisition Credit Facilities may not be
re-borrowed. The Acquisition Credit Facilities agreements contain customary representations and warranties and affirmative and negative covenants of Hydro One that are consistent with those of Hydro One’s
Operating Credit Facilities. If the Merger does not close, then these agreements will be cancelled. 
 To mitigate the foreign currency risk related to
the portion of the Avista Corporation acquisition purchase price financed by the issuance of convertible debentures, in October 2017, the Company entered into a deal-contingent foreign exchange forward contract to convert $1.4 billion Canadian
to US dollars. For the nine months ended September 30, 2018, an unrealized fair value gain of $25 million was recorded related to this contract, compared to an unrealized fair value loss of $3 million recorded for the year ended
December 31, 2017. At September 30, 2018, the corresponding derivative asset was $22 million, compared to a derivative liability of $3 million at December 31, 2017. 

The cash purchase price of the Merger and the Merger-related costs are expected to be financed at the closing of the Merger with a combination of some or
all of the following sources: (i) net proceeds of the first instalment from the sale in August 2017 of $1.54 billion aggregate principal amount of 4.00% convertible debentures of the Company represented by instalment receipts;
(ii) net proceeds of any subsequent bond or other offering; (iii) amounts drawn under the existing $250 million operating credit facility of the Company; (iv) amounts drawn under the $1 billion
non-revolving equity bridge credit facility; (v) amounts drawn under the US $2.6 billion non-revolving debt bridge credit facility; (vi) net proceeds of
any offering of securities from the Company’s Universal Base Shelf Prospectus; and (vii) existing cash on hand and other sources available to the Company. 

Compliance 
 At September 30, 2018, the Company was in
compliance with all financial covenants and limitations associated with the outstanding borrowings and credit facilities. 
 Credit Ratings 

Following the announcement of the Avista Corporation transaction on July 19, 2017, various ratings organizations undertook a review of the
Company’s and Hydro One Inc.’s debt ratings. These ratings organizations may take various actions, positive or negative. The Company cannot predict what actions rating agencies may take in the future. The failure to maintain the
Company’s current credit ratings could adversely affect the Company’s financial condition and results of operations, and a downgrade in the Company’s credit ratings could restrict the Company’s ability to access debt capital
markets and increase the Company’s cost of debt. 
 On June 20, 2018, Moody’s Investors Service (Moody’s) downgraded the long-term
debt rating for Hydro One Inc. to “Baa1” from “A3”, and revised its outlook on Hydro One Inc. to stable from negative. In addition, Moody’s affirmed the existing “Prime-2”
short-term debt rating for Hydro One Inc. Moody’s no longer assigns any probability of extraordinary support from the Province of Ontario (Province) in Hydro One Inc.’s credit analysis which has led to the downgrade. 

On June 15, 2018, S&P Global Ratings (S&P) placed its ratings on the Company and Hydro One Inc. on CreditWatch negative reflecting the
likelihood of a one-notch downgrade to both companies due to the Avista Corporation transaction. On July 18, 2018, S&P released an update maintaining the CreditWatch negative placement, which
continued to reflect the likelihood of a one-notch downgrade in the Company and Hydro One Inc.‘s issuer credit rating of “A” due to the Avista Corporation transaction, and also incorporated the
possibility that the Company’s governance structure could result in an additional one-notch downgrade if S&P concludes that recent developments related to the retirement of the Company’s Chief
Executive Officer (CEO) and the replacement of the Company’s Board of Directors (Board) adversely impact management decision making and fails to promote the interests of all stakeholders. See section “Hydro One Board of Directors and
Executive Officers” for more information.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

On September 13, 2018, S&P lowered its issuer credit ratings on the Company to “A-” from
“A”. At the same time, S&P lowered the issue-level rating on Hydro One Inc.‘s senior unsecured debt by one notch to “A-” from “A” and lowered the rating on Hydro One
Inc.‘s commercial paper program by one notch to “A-1(low)” from “A-1(mid)” on the Canadian National Scale. All ratings remain on CreditWatch
where S&P placed them with negative implications on June 15, 2018. The one-notch downgrade reflects S&P’s reassessment of Hydro One’s management and governance structure, which has
weakened following the Province’s decision to exert its influence on the Company’s compensation structure through legislation, potentially promoting the interests and priorities of one owner above those of other stakeholders. 

The following tables present the Company’s and Hydro One Inc.‘s credit ratings at September 30, 2018:

 SHARE CAPITAL 
 The common shares of
Hydro One are publicly traded on the Toronto Stock Exchange (TSX) under the trading symbol “H”. Hydro One is authorized to issue an unlimited number of common shares. The amount and timing of any dividends payable by Hydro One is at the
discretion of the Hydro One Board and is established on the basis of Hydro One’s results of operations, maintenance of its deemed regulatory capital structure, financial condition, cash requirements, the satisfaction of solvency tests imposed
by corporate laws for the declaration and payment of dividends and other factors that the Board may consider relevant. At November 7, 2018, Hydro One had 595,882,438 issued and outstanding common shares. 

The Company is authorized to issue an unlimited number of preferred shares, issuable in series. At November 7, 2018, two series of preferred shares
are authorized for issuance: the Series 1 preferred shares and the Series 2 preferred shares. At November 7, 2018, the Company had 16,720,000 Series 1 preferred shares and no Series 2 preferred shares issued and outstanding. 

The number of common shares of Hydro One that would be issued if all outstanding stock options and convertible debentures were converted as at
November 7, 2018 is 949,910 and 71,962,660, respectively. 
 REGULATION 

The OEB approves both the revenue requirements of and the rates charged by Hydro One’s regulated transmission and distribution businesses. The rates
are designed to permit the Company’s transmission and distribution businesses to recover the allowed costs and to earn a formula-based annual rate of return on its deemed 40% equity level invested in the regulated businesses. This is done by
applying a specified equity risk premium to forecast interest rates on long-term bonds. In addition, the OEB approves rate riders to allow for the recovery or disposition of specific regulatory deferral and variance accounts over specified time
frames.

inflationary increase (Price Cap Escalator factor) to its 2019 revenue requirement. 


  

	3 	 In June 2018, Hydro One Networks filed an undertaking with the OEB which included updated rate base amounts.



 Electricity Rates Applications 
 Hydro One Networks -
Transmission 
 On September 28, 2017, the OEB issued its Decision and Order on Hydro One Networks’ 2017 and 2018 transmission rates
revenue requirements (Decision), with 2017 rates effective January 1, 2017. Key changes to the application as filed included reductions in planned capital expenditures of $126 million and $122 million for 2017 and 2018, respectively,
in OM&A expenses related to compensation by $15 million for each year, and in estimated tax savings from the Initial Public Offering (IPO) by $24 million and $26 million for 2017 and 2018, respectively. On October 10, 2017,
Hydro One Networks filed a Draft Rate Order reflecting the changes outlined in the Decision. 
 In its Decision, the OEB concluded that the net deferred
tax asset resulting from transition from the payments in lieu of tax regime under the Electricity Act (Ontario) to tax payments under the federal and provincial tax regime should not accrue entirely to Hydro One’s shareholders and that a
portion should be shared with ratepayers. On November 9, 2017, the OEB issued a Decision and Order that calculated the portion of the tax savings that should be shared with ratepayers. The OEB’s calculation would result in an

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

impairment of Hydro One Networks’ transmission deferred income tax regulatory asset of up to approximately $515 million. If the OEB were to
apply the same calculation for sharing in Hydro One Networks’ 2018-2022 distribution rates, for which a decision is currently outstanding, it would result in an additional impairment of up to approximately $370 million related to Hydro One
Networks’ distribution deferred income tax regulatory asset. The exposure from the potential impairments would be a one-time decrease in net income of up to approximately $885 million, resulting in
an annual decrease to FFO in the range of $50 million to $60 million. 
 In October 2017, the Company filed a Motion to Review and Vary
(Motion) the Decision and filed an appeal with the Divisional Court of Ontario (Appeal). In both cases, the Company’s position is that the OEB made errors of fact and law in its determination of allocation of the tax savings between the
shareholders and ratepayers. An OEB hearing of the merits of the Motion was held on February 12, 2018. On August 31, 2018, the OEB granted the Motion and returned the portion of the Decision relating to the deferred tax asset to an OEB
panel for reconsideration. Based on the assumptions that the OEB applies established rate making principles in a manner consistent with its past practice and does not exercise its discretion to take other policy considerations into account,
management is of the view that it is likely that the aforementioned tax savings will be allocated to the benefit of Hydro One shareholders. 
 In
October 2017, the intervenor Anwaatin Inc. also filed a Motion to Review and Vary the OEB Decision (Anwaatin Motion) alleging that the OEB breached its duty of procedural fairness, failed to respond to certain evidence, and failed to provide reasons
on the capital budget as it related to reliability issues impacting Anwaatin Inc.’s constituents. The Anwaatin Motion was heard by the OEB on February 13, 2018. Hydro One reached a settlement agreement with Anwaatin Inc. regarding the
Anwaatin Motion. On June 15, 2018, the settlement agreement was filed with the OEB for approval. 
 On November 23, 2017, the OEB approved the
2017 rates revenue requirement of $1,438 million. On December 20, 2017, the OEB approved the 2018 rates revenue requirement of $1,511 million, which included a $25 million increase from the approved amount, as a result of the OEB-updated cost of capital parameters. Uniform Transmission Rates (UTRs), reflecting these approved amounts, were approved by the OEB on February 1, 2018 to be effective as of January 1, 2018. 

In March 2017, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU)
2017-07, which limits capitalization of post-employment benefit related costs to the service cost component. Hydro One filed an application requesting the OEB to approve a regulatory asset, to record the
amounts no longer permitted for capitalization under the new standard, effective January 1, 2018. In May 2018, the OEB approved the regulatory asset. 

On March 16, 2018, the OEB issued a letter requesting Hydro One to file the transmission revenue requirement application for a four-year test period
from 2019 to 2022, rather than the minimum 5-year period allowed under existing OEB policy. The OEB indicated that it is more appropriate to consider rates for Hydro One’s distribution and transmission
businesses in a single application, and stated that it expected Hydro One to file a single application for distribution rates (including Hydro One Remote Communities Inc.) and transmission revenue requirement for the period from 2023 to 2027. 

A one-year inflation-based application for 2019 transmission rates was filed with the OEB on October 26,
2018. 
 Hydro One Networks - Distribution 
 The OEB
oral hearing related to Hydro One Networks’ application for 2018-2022 distribution rates was held on June 11-28, 2018. On July 20, 2018, Hydro One submitted its Argument-in-Chief. Intervenors had until August 10, 2018 to respond. On August 31, 2018, Hydro One filed its reply argument with the OEB. This concludes the evidentiary process with the exception of
pole attachment charges, and matters relating to recovery of certain amounts paid for executive compensation, as per the Hydro One Accountability Act (Act). See section “Hydro One Board of Directors and Executive Officers” for more
information. For both of these matters, the OEB issued a procedural order on October 12, 2018 outlining the next steps in the process throughout the fourth quarter of 2018. As part of these steps, on October 26, 2018, Hydro One filed a
submission with the OEB on how the Act impacts its distribution rate application. On November 2, 2018, Hydro One filed a submission with the OEB on the pole attachment charges. 

On June 27, 2018, the OEB issued a letter deferring Hydro One’s request for the OEB to approve an alternative method to calculate amounts
related to the post-employment benefit costs for Hydro One Networks’ distribution business until the next re-basing application is filed, as the OEB noted that the issue is relevant to both the
distribution and transmission businesses of Hydro One Networks. In the 2019 transmission rates application filed with the OEB on October 26, 2018, Hydro One requested this decision be made as part of its next transmission re-basing application. 
 B2M LP 

On May 10, 2018, the OEB issued its Decision and Rate Order on B2M LP’s 2018 transmission application reflecting revenue requirement of
$36 million, effective January 1, 2018. 
 Hydro One Remote Communities Inc. 

On March 19, 2018, the OEB approved the settlement agreement related to the 2018 rates application reached by Hydro One Remote Communities Inc. and
the intervenors in the rate proceeding. On March 26, 2018, a draft rate order was filed with the OEB for 2018 rates. The OEB approved the draft rate order on April 12, 2018, and the new rates were implemented effective May 1, 2018.

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

HOSSM 
 HOSSM is under a
10-year deferred rebasing period for years 2017-2026, as approved in the OEB MAAD decision dated October 13, 2016. On July 26, 2018, HOSSM filed a 2019 application to allow for inflationary increase
(Price Cap Escalator factor) to its previously approved revenue requirement. The Price Cap Escalator factor is designed to add inflationary increases to the revenue requirement on an annual basis. 

Niagara Reinforcement Limited Partnership (NRLP) 
 On
September 19, 2018, NRLP was formed to own and operate a new 230 kV transmission line, the Niagara Reinforcement Project, built to connect generators in the Niagara area and the load centres of the Greater Toronto and Hamilton areas. 

On September 27, 2018, Hydro One filed a transmission licence application with the OEB for NRLP. On October 25, 2018, Hydro One filed two other
applications with the OEB relating to NRLP requesting approval for Hydro One Networks to sell the applicable assets to NRLP and approval of interim rates to include in the 2019 UTRs. 

MAAD Applications 
 Orillia Power MAAD Application 

In 2016, Hydro One filed a MAAD application (2016 Application) with the OEB to acquire Orillia Power Distribution Corporation (Orillia Power) from the
City of Orillia, Ontario. On April 12, 2018, the OEB issued a decision denying Hydro One’s proposed acquisition of Orillia Power. The decision indicated that with the exception to pricing, the transaction met the no harm test.
Additionally, the OEB indicated that it required additional evidence on the overall cost structure following the deferral period and the impact on Orillia Power’s customers. On May 2, 2018, Hydro One and Orillia Power both filed a Motion
to Review and Vary the OEB’s decision, and on August 23, 2018, the OEB issued a decision upholding its April 12, 2018 decision to deny Hydro One’s proposed acquisition of Orillia Power. 

On September 26, 2018, Hydro One filed a new MAAD application (2018 Application) with the OEB to acquire Orillia Power. The evidence in the 2018
Application is similar to that provided in the 2016 Application, with the exception of updates to reflect current variables to costs and other metrics, as well as future cost structures. 

Peterborough Distribution MAAD Application 
 On October 12,
2018, the Company filed an application with the OEB for approval of the acquisition of business and distribution assets of Peterborough Distribution Inc. (Peterborough Distribution). On October 25, 2018, an advance ruling certification
application was filed with the Competition Bureau. See section “Other Developments - Peterborough Distribution Purchase Agreement” for more information on the acquisition. 

Other Applications 
 Lake Superior Link Project 

On February 15, 2018, Hydro One filed a Leave to Construct application with the OEB to construct the east-west tie line (EWT Line) in northwestern
Ontario (Lake Superior Link Project), which will compete with an application filed by NextBridge Infrastructure (NextBridge) to construct the EWT Line. Pursuant to the OEB’s direction, on July 26, 2018, the IESO issued its analysis of the
impacts of a delay to the in-service date for the construction of the EWT Line. In its analysis, the IESO recommends an in-service date of 2020 for the completion of the

 A combined OEB
oral hearing for the Hydro One EWT Line application, the Hydro One East-West Tie Station Expansion application, and the NextBridge EWT Line application was held on October 2-12, 2018. The OEB’s decision

 OTHER DEVELOPMENTS 
 Collective
Agreements 
 On March 1, 2018, Hydro One insourced its customer service operations, which had been previously outsourced to Inergi LP and

in 2017. 
 The current collective agreement with the PWU expired on March 31, 2018. On March 26, 2018, Hydro One and the PWU reached a
tentative agreement, and on June 27, 2018, the agreement has been ratified by the PWU. The term of the agreement is for two years ending on March 31, 2020.

 Avista Corporation Merger 

In July 2017, Hydro One reached an agreement to acquire Avista Corporation. The following table summarizes the status of the Merger approval process: 

 

			
	Approval Required	  	Status
	 Alaska1 
	  	 Approval received on June 4, 201810

	 Hart-Scott-Rodino Antitrust
	  	 Clearance received on April 5, 20185 

	 Federal Energy Regulatory Commission
	  	 Approval received on January 16, 20183 

	 Avista Corporation shareholders
	  	 Approval received on November 21, 20172



  

	1 	 On September 14, 2017, Hydro One and Avista Corporation filed applications with the state utility commissions in
Alaska, Washington, Idaho, Oregon, and Montana, requesting regulatory approval of the Merger on or before August 14, 2018. 


  

	2 	 On November 21, 2017, the Merger was approved by the shareholders of Avista Corporation. 



 

	3 	 On January 16, 2018, the Federal Energy Regulatory Commission approved the Merger application.



  

	4 	 On March 27, 2018, an all-parties,
all-issues settlement agreement was filed with the Washington Utilities and Transportation Commission. On July 12, 2018, the Washington Utilities and Transportation Commission gave notice of its intent to
conduct additional process, and on July 20, 2018, it gave notice that it is extending the deadline for a decision to December 14, 2018. On October 4, 2018, all parties to the settlement filed testimony in support of the settlement and
additional and modified commitments offered by Avista Corporation and Hydro One. A hearing on this matter was held on October 23, 2018. 


  

	5 	 On April 5, 2018, the 30-day waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, for the Merger expired. This expiration of the waiting period means that the parties have received antitrust clearance for the Merger and satisfies one of the closing conditions of the transaction.



  

	6 	 On April 13, 2018, a multi-party settlement agreement was filed with the Idaho Public Utilities Commission. On
July 20, 2018, the Idaho Public Utilities Commission ordered that a hearing initially scheduled for July 23, 2018 was vacated in response to the leadership changes at Hydro One announced in July 2018. A new hearing date has been set for
November 26-27, 2018. 


  

	7 	 On May 4, 2018, consent for the transfer of control of the wireless licences held by Avista Corporation and one of
its subsidiaries to Hydro One as a result of the Merger was received from the Federal Communications Commission. On October 3, 2018, the Federal Communications Commission granted an extension to consummate the transfer of control of the
wireless licenses to April 13, 2019. 


  

	8 	 On May 18, 2018, the Committee on Foreign Investment in the United States has completed its review of the proposed
merger, and has concluded that there are no unresolved national security concerns with respect to the Merger. 


  

	9 	 On May 25, 2018, an all-parties,
all-issues settlement agreement was filed with the Oregon Public Utility Commission. In response to the leadership changes at Hydro One announced in July 2018, one party no longer supports Hydro One’s
acquisition of Avista Corporation. On July 25, 2018, a new procedural schedule was adopted for the proceedings, setting a hearing for November 15-16, 2018, and a target date of December 14, 2018 for
a decision by the Oregon Public Utility Commission. 


  

	10 	 On June 4, 2018, the Merger was approved by the Regulatory Commission of Alaska, subject to certain conditions.



  

	11 	 On July 10, 2018, the Merger was approved by the Montana Public Service Commission, subject to certain conditions.



 Following the announcement on July 11, 2018 of the resignation of Hydro One’s Board and the immediate retirement of its
President and CEO (see section “Hydro One Board of Directors and Executive Officers” for more information), regulatory authorities in Washington and Oregon extended the timetable for arriving at a decision in Hydro One’s acquisition
of Avista Corporation to mid-December 2018. In addition, the Idaho Public Utilities Commission rescheduled its hearing from July 23, 2018 to November 26-27, 2018.
Applications for regulatory approval of the Merger are pending with utility commissions in Washington, Idaho, and Oregon. The settlement agreements remain subject to approval by the respective commissions. Also required is the satisfaction of
customary closing conditions. 
 The closing of the Merger is subject to the normal commercial risks that the Merger will not close on the terms
negotiated or at all. The completion of the Merger is subject to receipt of certain regulatory and governmental approvals, including the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, clearance of the Merger by the Committee on Foreign Investment in the United States, the approval by each of the Idaho Public Utilities Commission, the Public Service Commission of the State of Montana, the Public Utility Commission
of Oregon, the Regulatory Commission of Alaska, the Washington Utilities and Transportation Commission, the United States Federal Energy Regulatory Commission and the United States Federal Communications Commission (the status of which are noted
above), and the satisfaction or waiver of certain closing conditions contained in the Merger Agreement. The failure to obtain the required approvals or satisfy or waive the conditions contained in the Merger Agreement may result in the termination
of the Merger Agreement. There is no assurance that such closing conditions will be satisfied or waived. Accordingly, there can be no assurance that Hydro One will complete the Merger in the timeframe or on the basis described herein, if at all.
Failure to complete the Merger could expose Hydro One to litigation and resulting damages. The termination of the Merger Agreement may have an effect (which may be material and/or negative) on the price of the convertible debentures’ instalment
receipts and the Hydro One common shares, and will result in the redemption of the

For the three and nine months ended September 30, 2018 and 2017 
  

convertible debentures. If the closing of the Merger does not take place as contemplated, the Company could suffer adverse consequences, including the
loss of investor confidence, and may incur significant costs or losses, including an obligation to pay or cause to be paid to Avista Corporation a termination fee of US$103 million or other damages, which could be material. In addition, the
redemption of the convertible debentures would result in the related deferred financing costs being expensed immediately ($24 million at September 30, 2018), and the deal-contingent foreign exchange forward contract would be revalued to
$nil, which would result in a reversal of any previously recorded unrealized gains ($22 million at September 30, 2018). 
 Litigation 

Class Action Lawsuit 
 Hydro One Inc., Hydro One Networks,
Hydro One Remote Communities Inc., and Norfolk Power Distribution Inc. are defendants in a class action suit in which the representative plaintiff is seeking up to $125 million in damages related to allegations of improper billing practices.
The plaintiff’s motion for certification was dismissed by the court on November 28, 2017, but the plaintiff has appealed the court’s decision. The appeal was heard on October 16, 2018, and it is likely that the court will render
its decision before the end of 2018. 
 Litigation Relating to the Merger 

To date, four putative class action lawsuits were filed by purported Avista Corporation shareholders in relation to the Merger. First, Fink v. Morris,
et al., was filed in Washington state court and the amended complaint names as defendants Avista Corporation’s directors, Hydro One, Olympus Holding Corp., Olympus Corp., and Bank of America Merrill Lynch. The suit alleges that Avista
Corporation’s directors breached their fiduciary duties in relation to the Merger, aided and abetted by Hydro One, Olympus Holding Corp., Olympus Corp. and Bank of America Merrill Lynch. The Washington state court issued an order staying the
litigation until after the plaintiffs file an amended complaint, which must be no later than 30 days after Avista Corporation or Hydro One publicly announces that the Merger has closed. Second, Jenß v. Avista Corp., et al., Samuel v. Avista
Corp., et al., and Sharpenter v. Avista Corp., et al., were each filed in the US District Court for the Eastern District of Washington and named as defendants Avista Corporation and its directors; Sharpenter also named Hydro One, Olympus
Holding Corp., and Olympus Corp. The lawsuits alleged that the preliminary proxy statement omitted material facts necessary to make the statements therein not false or misleading. Jenß, Samuel, and Sharpenter were all voluntarily
dismissed by the respective plaintiffs with no consideration paid by any of the defendants. The one remaining class action is consistent with expectations for US merger transactions and, while there is no certainty as to outcome, Hydro One believes
that the lawsuit is not material to Hydro One. 
 Peterborough Distribution Purchase Agreement 

On July 31, 2018, Hydro One reached an agreement to acquire the business and distribution assets of Peterborough Distribution, an electricity
distribution company located in east central Ontario, from the City of Peterborough. Hydro One will pay the City of Peterborough $105 million for the transaction. The acquisition is conditional upon the satisfaction of customary closing
conditions and approval by the OEB and the Competition Bureau. On October 12, 2018, the Company filed an application with the OEB for approval of the acquisition.

For the three and nine months ended September 30, 2018 and 2017 
  

Blair Cowper-Smith was serving as the Corporate Secretary of Stelco Inc. (Stelco) in 2004. On January 29, 2004, Stelco filed for and was granted
Court bankruptcy protection under the Companies’ Creditors Arrangement Act (CCAA). Stelco emerged from Court protection under the CCAA on March 31, 2006. Blair also served as a Director of Golfsmith International Holdings GP Inc.
and Golf Town Canada Inc. (Golf Town) from 2016 to 2018. On September 14, 2016, Golf Town filed for and was granted Court bankruptcy protection under the CCAA. Golf Town emerged from Court protection after being sold to Fairfax Financial
Holdings Limited and CI Investments Inc. in October 2016. 
 Penalties or Sanctions 

None of the directors or executive officers of Hydro One or Hydro One Inc., nor any shareholder holding shares sufficient to materially affect control of
Hydro One or Hydro One Inc., has been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory
authority or been subject to any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor making an investment decision. 

Conflicts of Interest 
 To the best of Hydro One’s and Hydro
One Inc.’s knowledge, there are no existing material potential conflicts of interest among Hydro One or any of its subsidiaries and the directors or executive officers of Hydro One or any of its subsidiaries as a result of their outside
business interests as at the date hereof. Certain of the directors and executive officers serve as directors and executive officers of other public companies. Accordingly, conflicts of interest may arise which could influence these persons in
evaluating possible acquisitions or in generally acting on behalf of Hydro One or Hydro One Inc. Where conflicts arise, they are managed through a variety of measures, including declaration of the conflict, recusal from meetings and/or portions of
meetings, and the creation of separate board materials for the affected directors. 
 Interest of Management and Others in Material Transactions 

There are no material interests, direct or indirect, of any director or executive officer of Hydro One and its subsidiaries, or any associate or affiliate
of any of the foregoing persons, in any transaction within the three years before the date hereof that has materially affected or is reasonably expected to materially affect Hydro One or Hydro One Inc. 

Indebtedness of Directors and Executive Officers 
 No director,
executive officer, employee, former director, former executive officer or former employee or associate of any director or executive officer of Hydro One or any of its subsidiaries had any outstanding indebtedness to Hydro One or any of its
subsidiaries except routine indebtedness or had any indebtedness that was the subject of a guarantee, support agreement, letter of credit or other similar arrangement or understanding provided by Hydro One or any of its subsidiaries. 

Independence Matters 
 The Board of Hydro One and Hydro One Inc.
currently consists of 10 directors, all of whom are independent of Hydro One and Hydro One Inc. and independent of the Province within the meaning of the Governance Agreement. 

For Hydro One’s purposes, an independent director is one who is independent of Hydro One and independent of the Province. Directors will be
independent of Hydro One if they are independent within the meaning of all Canadian securities laws governing the disclosure of corporate governance practices and stock exchange requirements imposing a number or percentage of independent directors.
Pursuant to Canadian securities laws, a director who is “independent” within the meaning of applicable securities laws is one who is free from any direct or indirect relationship which could, in the view of the board, be reasonably
expected to interfere with a director’s independent judgement, with certain specified relationships deemed to be non-independent. A director will be “independent of the Province” if he or she is
independent of Hydro One under Ontario securities laws governing the disclosure of corporate governance practices, where the Province and certain specified provincial entities are treated as Hydro One’s parent under that definition, but
excluding current directors where the relationship ended before August 31, 2015. The Governance Agreement requires each of the directors, other than the CEO, to be both independent of Hydro One and independent of the Province. The Chair of
Hydro One is independent of Hydro One and the Province.

Board includes four female directors (40%).

 Audit Committee 

The Audit Committee must consist of at least three directors, all of whom are persons determined by Hydro One to be both “independent” (within
the meaning of all Canadian securities laws and stock exchange requirements and the Governance Agreement) and “financially literate” (within the meaning of other applicable requirements or guidelines for audit committee service under
securities laws or the rules of any applicable stock exchange, including National Instrument 52-110 - Audit Committees). At least one member of the Audit Committee will qualify as an “audit
committee financial expert” as defined by the applicable rules of the US Securities and Exchange Commission. The Audit Committee comprises William Sheffield (Chair), Anne Giardini, David Hay, Jessica McDonald and Russel Robertson. Each of the
Audit Committee members is independent and financially literate and each has an understanding of the accounting principles used to prepare Hydro One’s financial statements and varied experience as to the general application of such accounting
principles, as well as an understanding of the internal controls and procedures necessary for financial reporting. Russel Robertson and David Hay each qualify as an audit committee financial expert.  

Please refer to the biographies of our Audit Committee members described under “- Directors and Executive Officers” above for details of their
additional invaluable skills and experience. 
 Human Resource Committee 

Hydro One’s management team, the Human Resources Committee and the company’s compensation advisors all play a key role in determining executive
compensation for the company’s directors and executives and in managing compensation risk on behalf of the Board of Hydro One. The Human Resources Committee is responsible for assisting the Board in fulfilling its oversight responsibilities
relating to the attraction and retention of key senior management.

Please refer to the biographies of our Human Resources Committee members described under “- Directors and Executive Officers” above for details of their additional invaluable skills and experience. 



CEO Selection Committee 
 The Board has also formed an Ad-hoc CEO Selection Committee to identify and select a President and CEO. 
 Compensation Policies and Practices 

Other than as set forth in Hydro One’s management information circular dated March 19, 2018 prepared in connection with the annual meeting of
shareholders held on May 15, 2018 or as otherwise described below, there have been no material changes to the policies and practices adopted by the Board of Hydro One or Hydro One Inc. to determine compensation for Hydro One’s or Hydro One
Inc.’s directors and executive officers since January 1, 2018. 
 Changes to Hydro One’s Board and CEO Compensation 

As disclosed under “- Directors and Executive Officers” above, on July 11, 2018, Hydro One, on behalf of itself and Hydro One Inc.,
announced that it had entered into the Letter Agreement for the purpose of the orderly replacement of the Board of Hydro One and Hydro One Inc. and the retirement of Mayo Schmidt as the CEO effective July 11, 2018. In accordance with the Letter
Agreement, Hydro One has agreed to consult with the Province in respect of future matters of executive compensation. In addition, the then-existing Hydro One and Hydro One Inc. Board volunteered and agreed to immediately reduce board compensation to
the levels contemplated by the pre-January 1, 2018 director compensation policy. The then-existing Hydro One and Hydro One Inc. Board also volunteered and agreed to forego any compensation for their service
after June 30, 2018. 
 In connection with Mr. Schmidt’s retirement, he received amounts consistent with Hydro One’s retirement
policies applicable to his outstanding equity awards and his employment agreement as previously disclosed and was not entitled to severance. Mr. Schmidt received a $0.4 million lump sum payment in lieu of all post-retirement benefits and
allowances. 
 Bill 2 
 On July 16, 2018, the Legislative
Assembly of Ontario introduced Bill 2 (Bill 2) titled the Urgent Priorities Act, 2018. As an omnibus bill, among other matters, Bill 2, as proposed, would amend the Ontario Energy Board Act, 1998 (OEB Act) and enact the Hydro One
Accountability Act (Act), and would require the Board of Hydro One to establish a new compensation framework for the Board and certain executives of Hydro One and its subsidiaries (excluding subsidiaries incorporated outside Canada) in
consultation with the Province and the other five largest shareholders of Hydro One, which compensation framework is subject to approval by the Management Board of Cabinet. The Act provides the Management Board of Cabinet with the authority to issue
directives governing the compensation of directors and certain executives of Hydro One and its subsidiaries (excluding subsidiaries incorporated outside Canada). The introduction of Bill 2 may adversely impact Hydro One and Hydro One
Inc.’s ability to continue to attract and retain executives. 
 The Act also requires Hydro One to annually provide public disclosure concerning
compensation paid to certain executives, and provides that the OEB Act will be amended so that the rates charged by Hydro One and its subsidiaries shall not reflect amounts paid for compensation of the CEO and certain executives of Hydro One and its
subsidiaries. The impact of this amendment is expected to restrict Hydro One’s ability to recover certain amounts paid for executive compensation through separate rate mechanisms, which is estimated to result in a reduction in Hydro One’s
net income for the year ending December 31, 2018 of up to $9 million, and is subject to a final determination by the OEB. The reduction may be materially lower, depending on the determination by the OEB of the executives whose compensation
is to be excluded. Bill 2 expressly provides that certain causes of action and proceedings are not available or will be barred against the Province, Hydro One or any of its subsidiaries, or any of its current or former officers, directors, employees
or agents in respect of the Act, the Province’s involvement in compensation matters or other aspects of the corporate governance of Hydro One or any of its subsidiaries or any alleged misrepresentation in any prospectus, document or other
public statement related to the involvement of the Province in compensation matters at Hydro One or any of its subsidiaries. Bill 2 received Royal Assent on July 25, 2018.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

Province of Ontario 
 Notwithstanding the Governance Agreement,
and in light of actions taken by the Province following the provincial election in June 2018 including the passage of Bill 2, the Province may elect to make further decisions relevant to Hydro One that could be detrimental to the interests of
shareholders. 
 NON-GAAP MEASURES 

FFO 
 FFO is defined as net cash from operating activities,
adjusted for (i) changes in non-cash balances related to operations, (ii) dividends paid on preferred shares, and (iii) distributions to noncontrolling interest. Management believes that FFO is
helpful as a supplemental measure of the Company’s operating cash flows as it excludes timing-related fluctuations in non-cash operating working capital and cash flows not attributable to common
shareholders. As such, FFO provides a consistent measure of the cash generating performance of the Company’s assets.

 Adjusted Net Income and Adjusted EPS 

The following basic and diluted Adjusted EPS has been calculated by management on a supplementary basis which excludes income related to the Avista
Corporation acquisition from net income. Adjusted EPS is used internally by management to assess the Company’s performance and is considered useful because it excludes the impact of acquisition-related costs and loss or gain on the
deal-contingent foreign exchange forward contract. It provides users with a comparative basis to evaluate the current ongoing operations of the Company compared to prior year.

 FFO, basic and diluted Adjusted EPS, Adjusted Net Income, Revenues, Net of Purchased Power, and Distribution Revenues, Net
of Purchased Power are not recognized measures under US GAAP and do not have a standardized meaning prescribed by US GAAP. They are therefore unlikely to be directly comparable to similar measures presented by other companies. They should
not be considered in isolation nor as a substitute for analysis of the Company’s financial information reported under US GAAP.

 DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING 

Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting as
defined in National Instrument 52-109 Certification of Disclosure in Issuers’ Annual and Interim Filings. Internal control, no matter how well designed and operated, can provide only reasonable assurance
of achieving the desired control objectives and due to its inherent limitations, may not prevent or detect all misrepresentations. 
 There were no
changes in the Company’s internal control over financial reporting during the three months ended September 30, 2018 that materially affected, or are reasonably likely to materially affect, the Company’s disclosure controls and
procedures and internal control over financial reporting.

NEW ACCOUNTING PRONOUNCEMENTS 
 The following tables present
Accounting Standards Codification (ASC) guidance issued by the FASB that are applicable to Hydro One: 
 Recently Adopted Accounting Guidance 

 

									
	Guidance	  	Date issued	  	Description	  	Effective date	  	Impact on Hydro One
	ASC 606	  	May 2014 – November 2017	  	ASC 606 Revenue from Contracts with Customers replaced ASC 605 Revenue Recognition. ASC 606 provides guidance on revenue recognition relating to the transfer of promised goods or
services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services.	  	January 1, 2018	  	Hydro One adopted ASC 606 on January 1, 2018 using the retrospective method, without the election of any practical expedients and there was no material impact to the Company’s
revenue recognition policy upon adoption. The Company has included the disclosure requirements of ASC 606 for interim periods in the year of adoption.
	ASU 2017-07	  	March 2017	  	Service cost components of net benefit cost associated with defined benefit plans are required to be reported in the same line as other compensation costs arising from services rendered by
the Company’s employees. All other components of net benefit cost are to be presented in the income statement separately from the service cost component. Only the service cost component is eligible for capitalization where applicable.	  	January 1, 2018	  	Hydro One applied for a regulatory asset to maintain the capitalization of post-employment benefit related costs and as such, there is no material impact upon adoption. See Note 2 -
Significant Accounting Policies and Note 11 - Regulatory Assets and Liabilities in the Hydro One financial statements for the three and nine months ended September 30, 2018.
			
	Recently Issued Accounting Guidance Not Yet Adopted	  		  	
					
	Guidance	  	Date issued	  	Description	  	Effective date	  	Anticipated impact on Hydro One
	2016-02 2018-01 2018-10
2018-11	  	February 2016 – July 2018	  	Lessees are required to recognize the rights and obligations resulting from operating leases as assets (right to use the underlying asset for the term of the lease) and liabilities (obligation
to make future lease payments) on the balance sheet. ASU 2018-01 permits an entity to elect an optional practical expedient to not evaluate under ASC 842 land easements that exist or expired before the
entity’s adoption of ASC 842 and that were not previously accounted for as leases under ASC 840. ASU 2018-10 amends narrow aspects of ASC 842. ASU 2018-11 provides
entities with an additional and option transition method in adopting ASC 842. ASU 2018-11 also permits lessors to elect an optional practical expedient to not separate
non-lease components from the associated lease component by underlying asset classes.	  	January 1, 2019	  	The Company has reviewed a substantial number of existing leases and relevant contracts and continues its assessment activities. No quantitative determination has been made at this time. The
Company is on track for implementation of this standard by the effective date.
	2018-07	  	June 2018	  	Expansion in the scope of ASC 718 to include share-based payment transactions for acquiring goods and services from non-employees. Previously, ASC 718
was only applicable to share-based payment transactions for acquiring goods and services from employees.	  	January 1, 2019	  	Under assessment
	2018-13	  	August 2018	  	Disclosure requirements on fair value measurements in ASC 820 are modified to improve the effectiveness of disclosures in financial statement notes.	  	January 1, 2020	  	Under assessment
	2018-14	  	August 2018	  	Disclosure requirements related to single-employer defined benefit pension or other post-retirement benefit plans are added, removed or clarified to improve the effectiveness of disclosures in
financial statement notes.	  	January 1, 2021	  	Under assessment
	2018-15	  	August 2018	  	The amendment aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing
implementation costs incurred to develop or obtain internal-use software. The accounting for the service element of a hosting arrangement is not affected by the amendment.	  	January 1, 2020	  	Under assessment

 HYDRO ONE LIMITED 

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued) 

For the three and nine months ended September 30, 2018 and 2017 
  

FORWARD-LOOKING STATEMENTS AND INFORMATION 
 The Company’s
oral and written public communications, including this document, often contain forward-looking statements that are based on current expectations, estimates, forecasts and projections about the Company’s business and the industry, regulatory and
economic environments in which it operates, and include beliefs and assumptions made by the management of the Company. Such statements include, but are not limited to, statements regarding: the Company’s transmission and distribution rate
applications, including resulting decisions, rates and expected impacts and timing; the Company’s liquidity and capital resources and operational requirements; expectations regarding credit ratings; the Operating Credit Facilities; the
Acquisition Credit Facilities; expectations regarding the Company’s financing activities; the Company’s maturing debt; ongoing and planned projects, including expected results, costs and completion dates; expected future capital
investments, including expected timing and investment plans; contractual obligations and other commercial commitments; the OEB and applications before the OEB; the Company’s share capital and conversion of outstanding stock options and
convertible debentures; NRLP and the Niagara Reinforcement Project, the Lake Superior Link Project, and related regulatory applications; collective agreements; the pension plan, future pension contributions, valuations and expected impacts; impacts
of OEB treatment of post-employment benefit costs; dividends; estimated ETR; non-GAAP measures; internal control over financial reporting; recent accounting-related guidance; the Universal Base Shelf Prospectus; expectations relating to filing of a
future base shelf prospectus by Hydro One Holdings Limited; the convertible debentures; the Exemptive Relief; the status of the Company’s acquisitions and mergers, including Orillia Power, Peterborough Distribution and Avista Corporation; the
Company’s financing strategy and foreign currency hedging relating to the acquisition of Avista Corporation; class action litigation, including litigation relating to the Merger; the risk that the Company may fail to complete the Merger; the
Agreement with the Province; changes to Hydro One’s Board and CEO, and Bill 2 and its anticipated impacts, including expectations relating to executive compensation; and the potential of government intervention in Hydro One’s business.
Words such as “expect”, “anticipate”, “intend”, “attempt”, “may”, “plan”, “will”, “believe”, “seek”, “estimate”, “goal”, “aim”,
“target”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve assumptions and risks and uncertainties that are
difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed, implied or forecasted in such forward-looking statements. Hydro One does not intend, and it disclaims any obligation, to update any
forward-looking statements, except as required by law. 
 These forward-looking statements are based on a variety of factors and assumptions including,
but not limited to, the following: no unforeseen changes in the legislative and operating framework for Ontario’s electricity market or for Hydro One specifically; favourable decisions from the OEB and other regulatory bodies concerning
outstanding and future rate and other applications; no unexpected delays in obtaining the required approvals; no unforeseen changes in rate orders or rate setting methodologies for the Company’s distribution and transmission businesses;
continued use of US GAAP; a stable regulatory environment; no unfavourable changes in environmental regulation; no significant changes to the Company’s current credit ratings; no unforeseen impacts of new accounting pronouncements; and no
significant event occurring outside the ordinary course of business. These assumptions are based on information currently available to the Company, including information obtained from third party sources. Actual results may differ materially from
those predicted by such forward-looking statements. While Hydro One does not know what impact any of these differences may have, the Company’s business, results of operations, financial condition and credit stability may be materially adversely
affected. Factors that could cause actual results or outcomes to differ materially from the results expressed or implied by forward-looking statements include, among other things: 

Risks Related to the Avista Corporation Merger: 
  

	•	 risks relating to the Merger, including (i) the risk that Hydro One may fail to complete the Merger, (ii) uncertainty
regarding the length of time required to complete the Merger, (iii) the risk that the purchase price for Avista Corporation could increase, (iv) the risk that the anticipated benefits of the Merger may not materialize or may not occur within the
time periods contemplated by Hydro One; 


  

	•	 risks related to the financing of the Merger; and 



 

	•	 risks associated with the Province’s share ownership of Hydro One and other relationships with the Province,
including potential conflicts of interest that may arise between Hydro One, the Province and related parties. 


  

	Risks	 Related to the Business: 



 

	•	 risks associated with the Province’s share ownership of Hydro One and other relationships with the Province,

	•	 risks associated with the Province exercising further legislative and regulatory powers in the implementation of Bill
2; 


  

	•	 regulatory risks and risks relating to Hydro One’s revenues, including risks relating to rate orders, actual

	•	 the risk that the Company may be unable to comply with regulatory and legislative requirements or that the Company may
incur additional costs for compliance that are not recoverable through rates; 


  

	•	 the risk of exposure of the Company’s facilities to the effects of severe weather conditions, natural disasters or
other unexpected occurrences for which the Company is uninsured or for which the Company could be subject to claims for damage; 


  

	•	 public opposition to and delays or denials of the requisite approvals and accommodations for the Company’s planned

in the Indian Act (Canada)); 


  

	•	 the risks associated with information system security and maintaining a complex IT system infrastructure;



  

	•	 the risks related to the Company’s work force demographic and its potential inability to attract and retain
qualified personnel; 


  

	•	 the risk of labour disputes and inability to negotiate appropriate collective agreements on acceptable terms consistent
with the Company’s rate decisions; 


  

	•	 risk that the Company is not able to arrange sufficient cost-effective financing to repay maturing debt and to fund

	•	 the risk of a credit rating downgrade and its impact on the Company’s funding and liquidity;



  

	•	 risks associated with fluctuations in interest rates and failure to manage exposure to credit risk;

of the Company’s assets or to carry out projects in a timely manner; 


  

	•	 the risk of non-compliance with environmental regulations or failure to
mitigate significant health and safety risks and inability to recover environmental expenditures in rate applications; 


  

	•	 the risk that assumptions that form the basis of the Company’s recorded environmental liabilities and related
regulatory assets may change; 


  

	•	 the risk of not being able to recover the Company’s pension expenditures in future rates and uncertainty regarding
the future regulatory treatment of pension, other post-employment benefits and post-retirement benefits costs; 


  

	•	 the potential that Hydro One may incur significant expenses to replace functions currently outsourced if agreements are
terminated or expire before a new service provider is selected; 


  

	•	 the risks associated with economic uncertainty and financial market volatility; 



 

	•	 the inability to prepare financial statements using US GAAP; 



 

	•	 the impact of the ownership by the Province of lands underlying the Company’s transmission system; and



  

	•	 the risk related to the impact of the new accounting pronouncements.
